    Hi guys......

    somehting rather odd happened to me many years ago when I was at school in chemistry class. - I remembered (from an earlier year) about an experiement involving a white coloured gas and sulphur that smelled like rotten eggs.....

    ......so naturally when we were burning sulphur (and produced a white gas, which i think was sulphur dioxide, I had a good old sniff) - This resulted in my sinuses closing VIOLENTLY. - It was an involuntary reaction...... any idea what caused this ?


    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    Sulfur dioxide would react with the moisture in your nasal passage, turning into toxic sulfurous acid. You are lucky to be alive. Can't tell you why your sinuses closed...a defense mechanism perhaps?

    Wow! I did not realise that!! - I did go rather red in the face afterwards and my nose burned like hell - I wonder why they give these experiements to 13 year olds !!

    Sulphur dioxide does not smell like rotten eggs. Hydrogen sulphide does.
